Detailed Description
Provides a TCP/IP connection. Protocol is TCP, the mode is SOCK_STREAM, so this class should result in a reliable connection. This can be used to act as a client (link(0)) or as a server (link(n>0)). When acting as a server (i.e. waiting for requesting connections) you have to use {\ttsetMyPort()} to set the port this computer accepts connections on. The "clients" have to set their remote port numbers using {\ttsetRemotePort()} to the same value (who would have thought ...). Currently, \underline{all actions are blocking}. Thread safety has to be implemented if needed by the user.
Member Function Documentation
◆ link()
| bool goNet::goConnection::link | ( | int | maxconn = 0 | ) |
Tries to esablish a link. If maxconn = 0 it assumes to be connecting to a waiting computer. If maxconn > 0 it waits for maxconn computers to connect to it.
◆ recv()
| bool goNet::goConnection::recv | ( | void * | buffer, |
| int | length, | ||
| int | remote = 0, |
||
| unsigned int | flags = 0 |
||
| ) |
Receives a bulk of data in {\tt buffer} of length {\tt length} from the remote host number {\tt remote}. If {\tt maxconn} was larger than zero in {\tt link()}, you have to supply a remote host number you want to receive from.
◆ send()
| bool goNet::goConnection::send | ( | const void * | msg, |
| int | length, | ||
| int | remote = 0, |
||
| unsigned int | flags = 0 |
||
| ) |
Sends a bulk of data in {\tt msg} of length {\tt length} to the remote host number {\tt remote}. If {\tt maxconn} was larger than zero in {\tt link()}, you have to supply a remote host number you want to send to.
◆ setRemoteAddress()
| void goNet::goConnection::setRemoteAddress | ( | struct in_addr | addr | ) |
Sets remote adress. The current status is that {\ttlink()} always looks for the name set by {\ttsetRemoteName()} and never uses the raw address (who needs that anyway..).
